The oxygen behavior in the carbon nanostructures synthesized by CVD with recycling precursor

In this work, the recycled fraction of methanol from the rum distillation has been used to synthesize carbon nanostructures. The synthesis temperature variation results in different structures, where the oxygen, derived from the methanol molecule, plays an important role in the nanostructures surface properties. The synthesis was carried out by chemical vapor deposition at 750, 800 y 850 °C. The characteristic peaks of the carbon nanostructures were noted by the Raman analysis and the functional groups were confirmed by the Fourier transform infrared spectroscopy. The synthesis of carbon nanostructures by CVD from recycled methanol allows oxygen to be incorporated on its surface.
